27 red ones which make up 60%

Question

What is the answer

 

Answer 1

The question is a little too brief, but if you're asking what the total of all "ones" was, it's easy! Use the formula:

Part / Whole   =   %  / 100

In this case, the 27 "red ones" make up only a part of everything, so it goes on top. When using the formula, do not write the percent sign; the 100 on the bottom is the sign in disguise.

27 / X  = 60 /100

Cross-multiply, which is always the first step in these problems:

2700 = 60X

 /60    /60

  45   =  X
